Matching sets include an upper receiver and hand guard that's ready to install onto your gun. The matching hand guard includes MLOK mounting points for accessories like lights and lasers, and the upper receiver has a Magpul M-LOK compatible design. Every surface of the hand guard is precision machined and chamfered to ensure no uncomfortable, sharp edges are found. The Cerakote finish gives a perfectly matching finish. The 7075-T6 billet aluminum upper receiver is precision CNC machined as a matching set.
